JOHN FRANCIS HERO, OF NEWARK. OHIO- ILUE TURNING AND READING TOOL.

Specification of Letters Patent. Application Med April 10, 1811.

Patented Feb. 6, 1.912. Serial No. 620,080.

To all whom it may concern:

Be it known that I, Jonx F. Geno, a citizen of the United States.residing at Newark, in the county of Licking and State of Ohio. haveinvented certain new and useful Improvements in Flue Turning and BeadingTools; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enab e others skilledin the art to which it appertains to make and use the same.

This invention relates to tools for operating upon fines, and moreparticularly to a combined turning and beading tool for fines ofdifferent diameters.

An object of the invention is to combine the turning and bending tools,making one tool for the two pur oses and enabling the workman to turn anbend a fine with one operation of the single tool.

Another ob'ect is to devise a tool which will serve as 0th a flueturning tool and a fine beading tool and which will therefore both turnand bend the fiue in one operation in about half the time now requiredto turn the flue with a fine turning tool and then bend the flue with aflue beading tool, making two separate operations, and,

A further ObJtCt is to provide a tool of the above stated characterwhich will be extremely simple in construction and operation and whichwill be easy and cheap to manufacture.

Other objects and advantages will be hereinafter set forth and pointedout in the specification and claims.

In the accompanying drawings which are made a part of this application,Figure 1 is a view of the tool ap died to one end of a flue to turn andbead t lc latter. Fig. 2 is a plan view at right angles to Fig. l. thetool being removed from the end of the flue, Fig. 3 is an end view ofthe tool. looking at the rounded end thereof. and, Fig. 4 is an end viewof the same, looking at the workin end of the tool.

Tleferring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views. the tool consists ofthe rounded shank portion 1 and the octagonal shaped central portion 2,from which extends the tint beveled sides 3 of the turning and headingend of the tool.

At right angles to the tint beveled sides 3 are the slightly flaredsides 4, one of the sides 4 extending beyond the opposite side 4, thepurpose of which will presently appear.

The beveled sides 3 converge to within about three-eighths of an inch attheir outer extremities. while the sides 4 are about one inch apart attheir outer extremities. thus forming a working or line engaging end ofabout three-eighths of an inch thick and about one inch wide. Thedimensions, however, may be varied as desired, but it is preferred tohave the proportions about the same as just described.

From the short side 4 the flue engaging end is straight and directed atan angc to the side 4 for a short distance, as shown at 5. From theinner edge of the portion 5 the flue engaging end is directed inwardlvand curred in semicircular form, to )rovide the flue end receivingrecess 6, an from the portion 6 the engaging edge is curved ontwardly topresent the curved flue entering portion 7, which connects with the longside 4 of the working end of the tool. Thus. it will be seen that theworking end of the tool is provided with a straight ortion 5 connectedwith the short end 4 and directed at an angle thereto. a centralsemicircular nick or flue end receiving recess 6 connected with thestraight portion 5. and. beginning at this point and also connected withthe outward v curved flue entering or convex portion which connects withthe long straight edge 4. The shank 1 is adapted to be engage with apneumatic hammer, as will be understood.

The operation of the tool is as follows: The working end of the tool isplaced against the end of the flue to he turned and headed. in suchposition that the edge of the flue rests within the semicircular nick 6.the straight portion 5 being outside of the flue. while the long curvedortion 7 is within the flue. The tool. as will be understood, is held bythe operator. in the proper position and. while held in this position.is caused by the pneumatic hammer. to pound upon the end of the line toturn and bend the same. As the tool is held in this position and forcedagainst the heated and of tho the working and of the tool will, by beingheld roperly. curve the edge of the line outwart ly and, the sharp edge,at the junction of the straight portion 5 and semicircular portion twill force the edge of the line, as it is turned or curved against theboiler head and form the. end into a head, making a water tightconnection between the boiler head and the turned and headed end of theline.

It will be understood that the tool is moved around the edge of the lineend. turning and bending the end gradually. On account of the strai ht.portion 5 of the working end of the tool heing directed at. an angle ofmore than 90. the end of the line, as it is forced by the tool to turnoutwardly, will be )rcssed tightly a ainst the boiler head and. thus,the bead wi i be formed out of the end of the line, as the latter isturned, accomplishin two resnlts with one operation of one too This, itwill be seen, eliminates the necessity of first turning the end of thefine with one tool and then beading the tine with a second tool,requiring two separate operations and a double amount of time as well aslabor.

Thus, it will be seen that my combined flue turning and beading tooleliminates the necessity of having separate tools for these twooperations, and also saves the double labor and makes it ossible toperform this work in one-half t 1e time heretofore required, cutting theexpense of such work in half as well as the price of the implementsnecessary.

This tool may be eflectively used for turning and beading the ends ofeither cold or heated fines of various diameters.

It. will be readily seen that as the working end of the tool is ofsubstantially rectangular form in cross section and only aboutthreeeighths as wide across the flue end receiving recess, or nick, asthe width at right. angles thereto, or from one straight edge 4 to theother straight. edge 4, there will only be an extremely small portion ofthe edge of the due engaged at. one time. Thus, the force or power willbe concentrated and applied directly to only an extremely small portionat one time. the tool being moved around the edge of the flue as thelatter is turned and headed in the one operation. Owing to the culiarconstruction of the working end of this tool, the same may beeffectively used for turning and heading the ends of lines of variousdiameters. eliminating the necessity at duplicating the ditl'erent sizesfor the lines of diti'erent diameters, as is-now necessary with the somratc tluc turning tools and tlue beading too s in general use.

In operation the tool is preferably held in the position shown in Fig. l(in divert alinement with the flue) and driven straight forward, thecurvature of the working and of the tool ro wrly turning and heading thecd e of t it. line as the tool is moved around said edge. It will beevident. however, that if desired, the tool may be held at, variousangles during the operation, the same as the tools now in use, but thisis not at all necessary.

It will be evident that with this tool, which enables the concentrationof the power and force to only a small portion of the edge of the lineat one time, the work will be much more ell'ective and more readilyaccomplished than is now possible with the present form of line turningtools and lluc beading tools which engage the entire end of the line atone time.

What I claim is:

A tool for turning and heading a line, comprising a shank portion, acentral portion integral with said shank portion, a working cud integralwith said central portion opposite said shank ortion, said workingportion having opposite converging beveled sides and o posite arailelstrai ht sides atright nu l; es to said beveled sides, one of saidstraig it sides being shorter than the opposite straight side, saidworking ortion aving a flue-enga ing end with which said sides connect,said flue-engaging end having a semicircular flue-receiving recess, anoutwardly curved flue entering portion connecting with said semicircularrecess and the lon straight side of said working end, and a shortstraight portion for said engaging end connecting with the semicircularrecess and with the short straight side, said straight portion being atan angle to said short strai ht side.

2. A too for turning and beading a line, comprising a shank portion, acentral portion integral with said shank portion, a
